|Aquaman's Doomsday Weapon|
|Appeared in||Justice League: The Flashpoint Paradox|
Aquaman's Doomsday Weapon is a weapon of mass destruction that destroy entire continents Aquaman used it twice in his war with the Amazons.
In the Flashpoint timeline, Aquaman commissioned a doomsday device to use against Wonder Woman and the Amazons. Its blast yield was powerful enough to wipe out continents. Captain Atom attempted to stop Aquaman but he was defeated and used against his will as the device's power source. When a fraction of its power was used, the shockwave generated devastated most of Europe but had no effect on New Themyscira, protected by a magic barrier. Dr. Vulko felt it was too dangerous to use again and convinced Aquaman to hold off on using it due to instability issues. Rather than risk sweeping the ocean floor clean, Aquaman ordered for a surface invasion. Hal Jordan was assigned to conduct a kamikaze attack on the doomsday device but Aquaman ordered a giant serpent to swallow Jordan and Abin Sur's repurposed ship whole. As Aquaman lay on the verge of death, he activated the device by his belt buckle just as Dr. Vulko attempted to free Captain Atom. Just as the blastwave engulfed New Themyscira, the Flash ran fast enough to travel to the past to prevent this disaster from ever happening.
